SureDrill™Real Time Drilling Optimization

SureDrill is a drilling optimization service thatcombines drill string modeling with real timesurface and downhole drilling data to optimizedrilling parameters.

APS Technology’s SureDrill serviceoffers real time predictive, closed-loop drilling optimization thatmaximizes ROP and extends bitruns, resulting in lower drilling costs.ROPs increases up to 70% havebeen achieved on several wells.SureDrill identifies drillingdysfunctions early so the driller cantake corrective action and avoidunplanned trips.

In addition to cutting drilling time,SureDrill also improves hole qualityand reduces wear and tear on drillstring components, minimizingredress charges.

Benefits:> Increased ROP> Longer Bit Runs> Fewer Trips> Reduced Wear & Tear> Less DBR Charges

Without Optimization With Optimization

Case Study: Drilling plan called for 25 days and two unplannedtrips. SureDrill & APS:

> Saved eight drilling days> Correctly identified balled bit> Correctly recommended against bit run

SureDrill™

About APS’s MWD SystemAPS’s SureShot family of directional and directional plus gamma systems provides reliableand flexible measurement-while-drilling performance in combination with our second-generation Rotary Pulser. The system can be powered by our battery modules, our turbinealternator, or a combination of the two. This MWD system provides highly accurate azimuthand inclination data for all applications from straight-hole through horizontal drilling.Rapid and accurate toolface transmission enables the most complex well paths to bedrilled with confidence.

SureShot’s downhole portion includes a rugged directional sensor package with NIST-traceable magnetometer calibration; a reliable, field-proven, Rotary Pulser*; and battery and/or turbine alternator for power. SureShot’s modular design allows theaddition of other functions like high-quality gamma and/or vibration logging. Each packageis protected by a state-of-the-art vibration isolation system and is mounted in berylliumcopper or high-strength steel pressure barrels. A small, robust surface decoder interfaceswith a computer running APS’s SureShot Control Center software. The SureShot MWD canstore up to 32 MB of MWD/LWD and diagnostic data for retrieval during trips.

SureShot’s patented second-generation Rotary Pulser* is the toughest, most advanced,most LCM-tolerant mud pulse transmitter in the industry. Our pulser’s ultra-reliable, high-efficiency DC brushless motor and controller, single open-flow path,positive pulse output and anti-jamming control virtually eliminates jamming or blockage, and the on-board memory allows post-run analysis of pulser performance.The Rotary Pulser is easily converted between fixed-mount and retrievable configurations.

The SureShot system is easy to learn, assemble and operate. In fact, APS’s customers frequently train their personnel themselves to operate our system.

> The highly reliable APS second-generation Rotary Pulser converts easilyfrom fixed-mount to retrievable, providing fixed-mount reliability or retrievablelost-in-hole security.

> Additional sensors including gamma, vibration monitoring and resistivitycan be quickly incorporated into our “LWD-Ready” system.

> The surface system presents data in a simple, user-friendly control anddisplay module. The data is transferred to a central control PC from whichit can be directed back to a dedicated wireless rig-floor display and/orrig monitoring system.

> Multiple encoding schemes and advanced decoding enable rapidcustomization of the data stream for maximum speed or maximumdata integrity.

> The unique APS power management module enables the system to bepowered through dual battery packs or a combination of battery power andAPS turbine alternator †.
